    • A method for forming color images and silver halide color photographic material for use therewith are provided by the present invention. The method comprises imagewise exposing a silver halide color photographic material processing with a color developer and then successively processing with a solution having a bleaching ability and having a pH of about 6.5 or less for a period of time of about 75 seconds or less, wherein the silver halide color photographic material contains at least one light-sensitive layer on a support, the light-sensitive layer containing at least one coupler capable of forming a dye by the coupling reaction with the oxidation product of an aromatic primary amine color developing agent and a silver halide emulsion which substantially excludes silver iodide but contains silver chloride in an amount of about 80 mol % or more and which has been spectrally-sensitized with a dye as represented by general formula (I), (II) or (III) described herein. The characteristic aspect of the present invention includes the high spectral sensitivity, the sufficient color forming property and desilvering property almost without the generation of fog, and the possibility of the rapid processing with a color developer which does not substantially contain benzyl alcohol.
